Poodoku

Poodoku is a cozy logic-puzzle whodunit for the whole family.

Someone pooped in the house. You have a small cast of suspects, a floor plan, and a handful of clues. Read each clue, place each suspect in the right room, and the last empty square is the poop — the room it's in reveals the culprit.

Every day brings three fresh puzzles — Easy, Medium, and Hard — across a 365-day archive so you can catch up whenever life gets busy. When you're ready to level up, Hard+ teasers open the trickiest 5-room grids.

WHAT MAKES IT TICK
Poodoku borrows the "one per row, one per column" backbone from sudoku or queens and pairs it with logic clues from a whodunit — "I was on the sofa," "I was beside the plant," "I was in the same room as Milo." Every puzzle is uniquely solvable through pure deduction. No luck. No shortcuts to the answers.

FEATURES
• New puzzles every day + full archive
• Three difficulties every day, plus Hard+ bonus grids
• Interactive tutorial that teaches the whole clue vocabulary
• Streak tracker with an optional 7pm reminder
• Mark cells with an X while you think
• Drag-and-drop, auto-mark, and candidate-location hints — pick the input style that fits you
• Light + dark mode, storybook art, big-tap targets
• Optional Cats Pack: swap the default cast for 20 hand-drawn cat suspects

FAMILY FRIENDLY
Poodoku's puzzles are kid-approachable without dumbing anything down. It's the kind of game a 7-year-old and a grown-up can solve together on the couch. Cute art, gentle stakes ("someone had an accident"), no violence, no ads.

QUIET, RESPECTFUL DESIGN

• No account required, we respect your privacy and don't sell your information
